Storage Design for Business Continuity
First Previous Next Last

Virtual Storage is storage presented to virtual I/O servers which in turn present this storage wholly or partially to a Virtual LPAR.

In this scenario Virtual I/O Servers act as the SAN or storage management subsystem in storage presentation to LPARs.

Virtual I/O Server is an AIX based platform that runs within an LPAR and is restricted to the Power5/6/7 technology at this time.

Physical storage is presented to the Virtual I/O Server which in turn reallocates the storage to the virtual LPARs.

The Physical storage can be SAN, internal or external disks.

Virtual storage presentation is viewed by the virtual LPAR as a standard (virtual) SCSI drive.

The Virtual I/O Server can present entire disks or logical volumes as storage to a virtual LPAR.
